Aquesta línia de recerca té com a objectiu estudiar la dinàmica de règims preturbulents o de turbulència plenament desenvolupada. Per extensió, s'estudien problemes associats amb la dinàmica no lineal d'ones, sistemes complexos, formació d'estructures dissipatives (patterns), etc. La major part dels problemes objecte d'estudi corresponen a sistemes d'interès geofísic o de recerca bàsica, és a dir, oceanografia, dinàmica atmosfèrica, dinàmica mediambiental, però també són objecte d'estudi alguns models matemàtics d'interès físic o biològic susceptibles de propagar ones, fronts, polsos, defectes, etc. Com a exemple de problemes en estudi podem esmentar la convecció tèrmica, la turbulència en fluids estratificats, els sistemes en rotació, la dinàmica de mescles, l'arrossegament de sediments, els corrents de gravetat, etc. Quant a les tècniques que s'utilitzen, en el camp de la teoria es combina la simulació numèrica directa de processos amb tècniques analítiques de reducció a formes normals, equacions d'amplitud, dinàmica caòtica, etc. En el terreny experimental, la tècnica més emprada és el tractament digital d'imatges de fluxos obtinguts en experiments de laboratori.
